Abstract

Following the dragon fruit, Vietnamese rambutan has been permitted to enter USA market since 2011 and irradiation is defintely required as one of the compulsory conditions for fresh produces before entering USA market. At present, the irradiation dose for rambutan quality in Vietnam condition has been studied. Therefore, an investigation on the impacts of the permitting low-dose irradiation (from 200Gy to 500 Gy) and packaging (carton or carton + holed PE bags) on Java rambutan quality grown from GAP in Vietnam was conducted. The result indicated that a dose of 300Gy improved the color of rambutan pericarp as compared to control (unirradiated) and other low doses including 400 Gy during storage at 13±1oC. In addition, the packaging condition of holed PE bag placed in 2kg carton box also improved (color prserved better) the pericarp color as well as reduced weight loss during storage at 13±1oC
Keywords: rambutan, low-dose irradiation, pericarp color
